Top facts about the Indian River Lagoon

Watershed

The lagoon watershed is home to 2,284 square miles of amazing natural beauty, and its waters span an impressive 353 square miles.

Five counties border the lagoon and seven counties are within the watershed.

The five inlets connecting the lagoon with the Atlantic Ocean create a flow of water between the two bodies of water. The inlet at Port Canaveral has locks that help to regulate the water exchange and keep the port basin separate from the lagoon.

The lagoon is a 156-mile-long estuary where salt water from the Atlantic Ocean mixes with freshwater from the land and tributaries. The resulting brackish (slightly salty) water is moved more by the wind than by the tide and does not flow from headwaters to a mouth like a river. The width of the lagoon can vary greatly, depending on the amount of freshwater flowing into it.
